Omron A16L-ARM-24-1 Pushbutton Switch - Equivalent & Substitute Parts

Part Overview

The Omron A16L-ARM-24-1 is a panel-mount illuminated pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 125V AC. This component is classified as obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

The primary reason for identifying substitute parts is the obsolete product status of the A16L-ARM-24-1, which may result in limited availability and extended lead times. Direct substitutes maintain electrical and mechanical compatibility while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the A16L-ARM-24-1 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Circuit configuration (SPDT), current rating (5A AC), and voltage rating (125V AC) must remain identical
• Mechanical Compatibility: Mounting type (Panel Mount, Front), panel cutout diameter (16.00mm), actuator type (Square, Button), and termination style (Solder, Quick Connect - 0.110") must match exactly
• Environmental Performance: Operating temperature range (-10°C to 55°C), mechanical life (2,000,000 cycles), and electrical life (100,000 cycles) must be maintained
• Regulatory Compliance: RoHS compliance status must be equivalent or superior

The A16L-ARM-24D-1 qualifies as a direct substitute based on full alignment with these parameters. The primary difference is the illumination technology (LED vs. Incandescent) and illumination voltage specification (24 VDC vs. 24 VAC/DC), which does not affect the core switching functionality or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The A16L-ARM-24D-1 is the direct substitute for the obsolete A16L-ARM-24-1. Selection of this substitute is supported by:

• Product Status: The A16L-ARM-24D-1 maintains active product status with confirmed inventory availability (1160 pcs), eliminating supply chain risk associated with the obsolete A16L-ARM-24-1
• Regulatory Compliance: Both parts maintain RoHS compliance, ensuring continued adherence to environmental and regulatory requirements
• Functional Equivalence: Electrical ratings, mechanical dimensions, and operational characteristics are identical across all critical parameters
• Illumination Technology Difference: The substitution introduces LED illumination in place of incandescent technology. The illumination voltage specification changes from 24 VAC/DC to 24 VDC. This change does not affect the switching circuit operation and represents a technology upgrade with improved reliability and reduced power consumption

Frequently Asked Questions (FAQ)

Q: Can the A16L-ARM-24D-1 be used as a direct replacement for the A16L-ARM-24-1 in existing assemblies?

A: Yes. The A16L-ARM-24D-1 maintains identical electrical ratings (5A, 125V AC, SPDT), mechanical dimensions (16.00mm panel cutout), and termination style. Physical installation and electrical switching function are fully compatible.

Q: What is the difference between the illumination specifications?

A: The A16L-ARM-24-1 uses incandescent illumination rated at 24 VAC/DC. The A16L-ARM-24D-1 uses LED illumination rated at 24 VDC. Both provide red illumination. The LED version offers improved reliability and lower power consumption. If the illumination circuit is powered by AC voltage only, verify that the 24 VDC LED specification is compatible with your power supply configuration.

Q: Are there any mechanical compatibility concerns?

A: No. Both parts share identical panel mount specifications, 16.00mm circular cutout diameter, square button actuator type, and quick-connect termination style (0.110" / 2.8mm). Installation procedures and panel modifications are not required.

Q: What is the inventory status of each part?

A: The A16L-ARM-24-1 (obsolete) has 1062 pcs in stock. The A16L-ARM-24D-1 (active) has 1160 pcs in stock. The active status of the A16L-ARM-24D-1 ensures continued availability for future orders.

Q: Are both parts RoHS compliant?

A: Yes. Both the A16L-ARM-24-1 and A16L-ARM-24D-1 are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
